The battery on this beast of a device is insane. On light-moderate continious usage i get more than 12-13 hrs of screen time with a video playing on the background at all times. Most of what I do is efficiently executed in the abundance of efficiency cores. But the greatest thing is how the battery percentage stays the same for weeks on standby no matter what you had open in the background when you closed that lid. I remember times i havent had chance to open the laptop for 5-6 days, and most of the times the battery % is the same (only a single time when it dropped by only 1 percent). I have the 14" 12cpu/18gpu 36GB / 1TB model. If 14" is like this I can't imagine the battery life in 16"
